When a colony cluster is made, it takes the first 5 planets you have explored/conquered. I think It would be nice to be able to choose which planets you want to include and exclude from the colony cluster.
wouldnt it make things too easy? goes with the frustration and god knows how long of time spending, plus ud be able to strip mine way too easily etc nah i personaly beleavie as nice as the idea is, would make things too easy for cash etc and could spoil things
if you are a viral you can already do this by infecting only the planets you want in your cluster before clustering.
As for general use, i think that it would be useful but if it would be included it should probably be paid only(im not paid) as it wouild be very useful for clusters
